Question

我正在开发一个由mongodb支持的应用程序。无论是从shell还是以编程方式从应用程序进行与数据库服务器的交互都可以正常工作。问题是它只有在我以root身份运行服务器时才有效。否则它不起作用。在Windows上工作时我没有这个问题。我正在使用ubuntu 16.04。

首先，它是db路径，我更改了配置文件。然后它告诉我它无法创建锁文件，我更改了权限，（我不确定这是不是很好的做法），现在我有这个错误：

Detected data files in /data/db created by the 'wiredTiger' storage engine, so setting the active storage engine to 'wiredTiger'.

此外，当我尝试将其作为服务service mongod start运行时，它会抛出一个错误，即没有这样的服务文件。我在/ etc / systemd / system目录中创建了一个mongod.service文件但它仍然给出了相同的错误，没有这样的文件。

以下是systemctl status mongod的结果：

我遇到了同样的问题。

sudo systemctl start mongod似乎在我的环境中无效。

尝试sudo service mongod start它解决了我的问题。

使用sudo systemctl status mongod

给了我;

Mongod在ubuntu 16.04上崩溃
